Answer:
- waffle $8
- hashbrowns $1.50
Step-by-step explanation:
Using w and h for the costs of a waffle and hashbrowns, respectively, we can write the equations for the purchase amounts as ...
w + h = 9.50
2w + 3h = 20.50
Subtracting twice the first equation from the second gives ...
(2w +3h) -2(w +h) = (20.50) -2(9.50)
h = 1.50 . . . . . . simplify
w = 9.50 -h = 8.00 . . . . . find w using the first equation
The cost of a waffle is $8.00; the cost of hashbrowns is $1.50.
A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
